ceases.

To all whom it may concern:

Be it known that 1, JOHN BAADE, a citizen of the United States, residing at Waco, in the county of McLennan and State of Texas, have invented certain new and useful Improvements in Machines for Pressing Shingles and Slabs and the Like, of which the following is a specification.

This invention relates to machines for pressing shingles and other articles of building material from composition material, and the object is to provide simple and efficient machines for the manufacture of shingles and other articles of building material at small cost.

One of the objects of this invention is to apply enormous power by simple and inexpensive machines.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is a perspective view of the machine. Fig 2 is an end elevation of the same. Fig. 3 is a vertical cross section of the pressbox and of the table. Fig. 4 is a section of a plan view of the pressing slabs. Fig. 5 is a side elevation of one of the pressing slabs which has handles. Fig. 6 is a side elevation of one of the antifriction spacing blocks which are used between the pressing slabs. Fig. 7 is a section of the former box bottom and of a slab which are intended to make corrugated blocks of slabs. Fig. 8 illustrates the manner of placing forms on the bottom of the former box to out the shingles or slabs of any desired configuration. Fig. 9 is an end View of three bars of the pressing cover, showing the connecting rods. Fig. 10 is a detail view of the socket for the vertical shaft.

Similar characters of reference are used to indicate the same parts throughout the several views.

The machine is provided with a platform or table 1 which is supported by legs 2. Tracks 3 are provided for a movable former box 4. The material is placed in the box 4 to be formed and pressed. The box has a rack 5 attached to the bottom thereof which is to be driven by a cog wheel 6. The cog wheel 6 drives the rack 5 back and forth and thus reciprocates the former box on the Specification of Letters Patent.

frame. The former box may be provided with antifriction rollers 7 The cog wheel 6 is mounted on a shaft 8 which extends to one side of the machine to be driven by any suitable power. The material is pressed by a cover 9 made of slabs or bars of steel 10. These bars are made wider at the bottoms than at the top so that surface presented to the material will be smooth. Rods 11 run through the slabs or bars 10 to hold the same in operative relation or assembled. The holes 12 through the slabs 10 are elongated vertically to permit slight movement of the bars 10 on the rods 11. The bars 10 are pressed on the material by a roller 13 which is controlled by hydraulic pressure as here inafter set forth. The bars 10 will have a slight vertical movement on each other and in order to reduce the friction to a minimum, the slabs or bars are made narrower at the upper edges and antifriction spacing blocks 14 are placedbetween the bars 10. The spacing blocks 14 have cut-outs 15 to receive the rods 11 and they have two or more enlargements 16. The spacing bars with their enlargements prevent the pressing slabs or bars 10 from turning or tilting on the side when engaged by the roller 13. The roller 13 presses 011 the bars 10 with enormous power and the rollers must be braced against turning and friction must be avoided. Gearing is provided for driving the roller 13. The shaft 8 carries a beveled gear wheel 17 Wheel 17 drives a wheel 18 and wheel 18 drives the shaft 19. The shaft 19 carries and drives a bevel cog 20 and beveled cog 2O drives a beveled cog 21 which is mounted on the shaft 22 of the roller 13. The roller 13 is journaled in the arms 23 of a yoke 24 which is carried by the piston rod 25 of a hydraulic cylinder 26. The roller 13 isthus pressed down on the bars or slabs 10 by hydraulic pressure. The cog wheel 21 will necessarily have a slight vertical movement. For this reason the shaft 19 is supported on powerful springs 27 which are mounted in a hollow shaft 28 which carries the bevel gear wheel 18. The springs will permit sufficient depression of the bevel gear wheels 20 and 21 to allow the roller 13 to press the material in the former box 4.

In manufacturing the compressed material the sheets may be as large as the bottom of the former box or forms 29 may be placed on the bottom of the former box to cut the sheet into any desirable size and of any desirable configuration. The ingredients which form the composition for the shingles or Whatever articles are to be manufactured are reduced to the proper consistency and placed in the former box. The cover consisting of the pressing 'bars above described is placed on the prepared material. The material is then ready to be pressed by the roller 13. The former plate is then passed back and forth under the roller by means of the gearing above described until the material has been sufficiently packed. It is preferable to make one sideand one end of the former box detachable because the material becomes packed close and hard in the box and it is necessary that access be had to the lower edge of the formed material so that it can be removed from the box.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is, 1. A shingle making machine having a frame, a former box movable on said frame, a cover for said box consisting of bars lying with the fiat faces toward said box, rods running through said bars, a compression roller journaled above the path of said box, means for reciprocating said box under said roller, and means for applying hydraulic pressure to said roller.

2. A shingle making machine having a frame, a former box movable on said frame, gearing for reciprocating said box on said frame, a cover for said box consisting of bars tapering from the bottom upwardly, rods running loosely through said bars, spacing blocks between said bars, and means for pressing said cover on said box.

3. A shingle machine having a frame, a former'box movable on said frame, a cover for pressing on material in said box, a pressing roller mounted above the path of said box, a rack on the bottom of said box and a gear wheel for reciprocating said box under said roller, means for applying hydraulic pressure to said roller, and means for driving said roller.

4:. In a shingle making machine provided with a frame and a former box movable on said frame, a cover for pressing material in said box consisting of a series of bars paral lel to each other and tapering from the bottom upwardly, antifriction spacing blocks between said bars, and rods running loosely through said bars.

In testimony whereof, I set my hand in the presence of two witnesses, this 8 day of July, 1909.

JOHN BAADE.
